System Requirements Check

⚠️ IMPORTANT NOTICE: THIS PLUGIN IS NO LONGER MAINTAINED ⚠️ Active development and support for System Requirements Check have officially ended.

• Why? The technical environment has evolved, making this plugin antiquated. Web standards have moved away from client-side technologies like Adobe Flash Player and Java Runtime Environment (JRE), which this plugin was originally designed to check. Modern web browsers and WordPress core now handle environment baseline checks natively, rendering this specific client-side check obsolete.
• Closing Date: This plugin will be officially closed to new downloads on the WordPress.org repository on December 31, 2026.
• What this means: No new features, bug fixes, or security patches will be released. The plugin is provided "as-is." Existing installations will continue to function but will receive no further compatibility updates.
• Support: The support forums will no longer be monitored.

Thank you to everyone who supported this project over the years! A system requirements plugin that checks for the specified version of the operating systems, web browsers, screen resolution, IP addresses, Adobe Flash Player, Java Runtime Environment (JRE), Cookie, and Javascript on the client's system. The result can be displayed on a post or page with the use of a shortcode to let the end-users be aware that their system may not be optimal for specific tasks or operations.
